#### Answer

7608 m$^2$

#### Work Step by Step

This figure consists of a large rectangle with two smaller and congruent rectangles cut out of it. The smaller rectangles have the dimensions of 12 m by 75 m. The large rectangle has a width of 64 m and a length equal to 36+75+36, which is 147 m. Therefore the area of the figure is equal the area of the large rectangle minus the areas of the smaller rectangles.
A=WL-2wl
A=64(147)-2(12)(75)
A=64(147)-(24)(75)
A=9408-(24)(75)
A=9408-1800
A=7608 m$^2$
